Timea Bacsinszky, twice a semi-finalist at Roland Garros, booked her place in the second round of qualifying for the French Open.
Following a string of injury problems, Swiss Bacsinszky has not played in the main draw of the clay court Grand Slam since 2017.
The 29-year-old, though, produced a vintage display to see off Hungarian Fanny Stollar 6-3 6-4 in their first-round match on Tuesday.
Bacsinszky, who found herself down from once in the world's top 10 to a low ranking of 761 last year, is one of 96 women players hoping to claim one of the 16 places on offer through qualifying.
"I'm very proud of how I've managed to come back and be fit again over this long time. I have no injuries now and I'm feeling good," Bacsinszky said, quoted on www.rolandgarros.com.
Elsewhere, 15-year-old reigning French Open Junior champion Cori Gauff progressed with a 6-4 6-4 win over world number 172 Ankita Raina.
Fellow teenager Whitney Osuigwe, the Junior French Open winner two years ago, produced a strong comeback as the 17-year-old beat Myrtille Georges 2-6 7-6 (3) 7-5 in a match which lasted two hours and 30 minutes.
There was, though, only one home player to progress from the seven in first-round games as Elsa Jacquemot defeated Basak Eraydin 6-3 6-1, while top seed Bernarda Pera beat Alize Lim 6-1 6-3.
Wednesday's action will see Britain's Heather Watson, seeded fifth, play Dutchwoman Bibiane Schoofs in the first match on Court 13, while Katie Swan takes on second seed Jil Teichmann.
In the men's event, top seed Tennys Sandgren came through his first-round qualifier with a straight-sets win over Yosuke Watanuki, the American progressing 6-2 6-4.
Ninth seed Ryan Harrison, though, is out following a 6-3 7-6 (5) 7-6 (5) defeat against Czech Adam Pavlasek while Australian Alex Bolt, the 18th seed, was beaten 6-2 6-2 by Spaniard Adrian Menendez-Maceiras.
Italian Paolo Lorenzi, the oldest player in the men's qualifying tournament, lost to Enzo Couacaud.
The Frenchman, who has fought his way back following elbow surgery, recovered from a set down to beat the 37-year-old 6-4 4-6 6-0.
There was also home success for Mathias Bourgue, who saw off Matteo Viola 4-6 6-1 6-3 and Geoffrey Blancaneaux, the 2016 French Open Junior champion, came through against Andrea Arnaboldi 7-6 (5) 3-6 6-3.
